Indonesia spans a number of islands in the Pacific that lie in the coffee growing belt. Sumatra is an island in Southeast Asia that is ideally suited for growing Arabica coffee beans. Sumatran coffees showcase how several factors influence a coffee beans taste profile.
Sumatra is the second largest island of the Republic of Indonesia. Sumatra Mandheling coffee although relatively rare is grown on the lofty volcanic slopes of Mount Leuser near the port of Padang in the Batak region of West Central Sumatra, at altitudes of 2,500 to 5,000 feet.
Sumatran coffee beans have a characteristic beautiful deep blue-green color with the appearance of jade, which is attributed to the processing method, “Gilling Basah” (wet hulling). The natural drying method used in its production results in a very full body with a concentrated flavor, garnished with herbal nuances and a spicy finish.
A Brief History of Sumatran Coffee
Indonesia was the first place, outside of Arabia and Ethiopia, where the coffee bean was widely cultivated. Coffee trees were originally brought to Indonesia by the Dutch who sought to break the worldwide Arabic monopoly in the cultivation of coffee. The Dutch governor in Malabar (India) sent a Yemeni or Arabica coffee (Coffee arabica) seedling to the Dutch governor of Batavia (now Jakarta) in 1696.
The first coffee seedlings failed due to flooding in Batavia. The second shipment of coffee seedlings was sent in 1699 with Hendrik Zwaardecroon. The coffee plants grew and in 1711 the first Sumatran coffee beans exports were sent from Java to Europe by the Dutch East India Company, known by its Dutch initials VOC (Vereeningde Oost-Indische Company). Within a few years, Indonesian coffee beans dominated the world's coffee market.
Today, more than 90% of Indonesia’s coffee is grown by smallholder coffee farmers on coffee farms averaging around one hectare. Some of this coffee production is organic and many coffee farmers cooperatives and coffee exporters are internationally certified to market organic coffee beans.
How does Sumatran Coffee Taste?
In general, coffees from Sumatra are known for their smooth, sweet body that is balanced and intense. Depending on the region, or blend of regions, the flavors of the land and processing can be very pronounced. Sumatran coffees capture the wild jungle essence of this tropical Indonesian island, which is why we chose the Sumatran Tiger as the image to represent this single origin Organic Sumatran Coffee. The Sumatran coffee has low-acidity and a smoothness and richness that lingers on the back corners of your tongue with notes of chocolate evident in the finish.

Processing Coffee Beans: Sumatran Coffee is Wet Hulled
Have you ever wondered how coffee is made? The coffee bean has quite a journey from plant to cup. A coffee bean actually comes from the coffee fruit, or what is referred to as the coffee cherry. There are a variety of methods used to remove the coffee bean from the coffee cherry. Wet hulling is the most common processing method used in Sumatra. Even though coffees processed this way are sometimes called natural or dry processed, wet hulling is distinct from natural processing methods used in other parts of the world, such as Ethiopia.
Wet hulling involves the following steps:
- Farmers remove the skin of the coffee cherry immediately after picking using homemade machines.
- The skinned coffee beans are placed in woven bags and left to ferment overnight
- The following morning, farmers wash off the mucilage (remaining fruit) by hand
- The coffee beans, in their parchment, are partially dried in the farmer’s yard
- The coffee bean is shipped to a warehouse, where the parchment is removed, and the coffee beans are dried more
- The coffee beans are shipped to a port city for exportation, and dried a third time at the port city
Wet Hulling leaves coffee beans moist for longer. Part of the reason the coffee beans aren’t dried by coffee farmers is because Sumatra has such a wet climate, which is great for growing coffee trees but poses processing challenges. In most coffee processing methods, coffee beans are dried until their moisture levels are between 9 and 11 percent when they leave the processing facility. Because wet hulling involves three stages of drying, the coffee’s moisture remains well above 11 percent for a long time — often until it’s finally exported.
Roasting Sumatra Coffee Beans
Most of Sumatran coffee’s unique characteristics stem from wet hulling. To enhance the coffees unique characteristics, and to counteract the high variance that’s introduced by a multi-stage processing method, John Weaver and his apprentice roasters, roast Sumatra Organic coffee beans dark. This builds on their body and adds a roast induced richness to the beans.
